I have got this keris from a person with great knowledge about keris and he has got it in Indonesia/Java like this. He also don't have had a explanation for it. I have some little understanding from my profession about metal and also in my eyes it seems very difficult to patch a small amount nickel on but what I can see happened exactly this. But I will try to take better pictures by daylight and hope that it is than to see what I see even that the pamor pool chipping from the iron and someone tried to repair it (at down it break again).

Thank you again,
